Dot product: For vectors a and b, a · b = |a||b|cosθ. Result is a scalar. Used for projections or checking orthogonality. Component form: a_x b_x + a_y b_y + a_z b_z. Cross product: a × b produces a vector perpendicular to both a and b. Magnitude = |a||b|sinθ. Used for torque, angular momentum, or surface normals in 3D.
